Now a proper home owner, I'm setting up something I've always wanted! Not so simple it turns out.

Room dimensions below in embedded PNG.

ceiling = 79"

The 12' distance is my general available space to put a projector. The 12' shown is from the front of the projector to the screen. The pull down (electric) must exist within the 30" offsets as shown to allow access to the cabinetry behind it (speakers are there).

70/30 Movies/Games

Room is light controlled well.

After hours of research, I came to the conclusion that I think I want the Sony 55ES, but that said I'm not terribly stuck on it. Just seemed like I could grow old studying the options and it was time to make a choice.

I ran into trouble when trying to spec the projector into the room to find the screen size. Namely, throw ratio information did not exist at projector central or on Sony datasheet itself. Does anybody know this information??

From the calculator from projector central, I'm substituting the 55ES for a 50ES because they don't have the 55ES in their options. Hence the question for the throw distance. When you input the 50ES, it returns the following information:

Sony HW50ES, 12' Throw

36deg viewing angle @ 11.1'

99" (8.25') diagonal, [49x86" HxL]

This will be a ceiling mount.

Can these projectors change the screen size? I was hoping to get 10' diag as I prefer sitting close, but if this isn't feasible or is flat out poor application I can live with the smaller sizes. Any guidance here is especially appreciated.

I have not purchased the proj/screen etc, so I'm still flexible. On that note, what are the best online sites to buy from?
